Sound field effects

The 6-channel soundtracks found on 70-mm fdni produce precise sound field localization and rich, deep sound without
using matrix processing. This unit's MOVIE THEATER programs provide the same quality of sound and sound

localization that 6-channel soundtracks do. The built-in Dolby Digital or DTS decoder brings the professional-quality
sound designed for movie theaters into your home. With this unit’s MOVIE THEATER programs, you can use Dolby

Digital or DTS technology to recreate a dynamic sound that gives you the feeling of being in a public theater.

These programs use YAMAHA's tri-field DSP processing
on each of the Dolby Digital or DTS signals for the front,

left surround, and right surround channels. This
processing enables this unit to reproduce the immense
sound field and surround expression of a Dolby Digital-

or DTS-equipped movie theater without sacrificitig the
clear separation of all channels.

Most movie material has 4-channel (left, center, right, and
surround) sound information encoded by Dolby Surround

matrix processing and stored on the left and right tracks.
These signals are processed by the Dolby Pro Logic
decoder. The MOVIE THEATER programs are designed
to recreate the spaciousness and delicate nuances of
sound that tend to be lost in the encoding and decoding
processes.

■ Dolby Pro Logic II

Dolby Pro Logic II decodes Dolby Surround software into 5 discrete full-range channels (3 channels in front and 2
channels in surround). There are 2 modes; MOVIE for movies and MUSIC for 2-channel audio sources.
